Abstract
In a multi-phase weaving machine, an apparatus (16) for monitoring warp yarn movement (3a, 3b) in particular leno warp yarns. The drawing-off movement or the drawing-off speed of the warp yarns (3a, 3b) can be detected by an electronic sensor (6a, 6b; 6c) so that it can in particular be determined whether the drawing-off movement or the drawing-off speed has a very low or relatively large value. If the value is very low, in particular when the warp yarn is standing still while the weaving process is running, it can be concluded that the warp yarn has broken. If the value of the drawing-off speed lies above a preset threshold value it can be concluded that the warp yarn is being driven in an undesired manner so that an error signal (13) is produced in order to interrupt the weaving process.
